Item 8.01 Other Events.

 

On December 9, 2008 we announced preliminary data from a Phase 2b clinical trial of APD125 measuring subjective endpoints in patients with primary insomnia. The initial data analysis indicates that APD125 did not meet the trial’s primary or secondary endpoints. Treatment with APD125 was well tolerated, and there were no reports of serious adverse events and no emerging safety findings as compared to placebo. We are finishing a complete analysis of the data, but do not anticipate any further development of APD125.

 

Forward-Looking Statements

 

Certain statements in this Form 8-K are forward-looking statements that involve a number of risks and uncertainties. Such forward-looking statements include statements about the results of the Phase 2b clinical trial of APD125, including the significance of such results, the further analysis of the Phase 2b clinical trial results and the future development of APD125. For such statements, we claim the protection of the Private Securities Litigation Reform Act of 1995. Actual events or results may differ materially from our expectations. Factors that could cause actual results to differ materially from the forward-looking statements include, but are not limited to, clinical trials and studies may not proceed at the time or in the manner we expect or at all, the results of clinical trials or preclinical studies may not be predictive of future results, our ability to receive regulatory approval for our drug candidates, our ability to partner lorcaserin or other of our compounds or programs, the timing, success and cost of our research, out-licensing endeavors and clinical trials, our ability to obtain additional financing, our ability to obtain and defend our patents and the timing and receipt of payments and fees, if any, from our collaborators. Additional factors that could cause actual results to differ materially from those stated or implied by our forward-looking statements are disclosed in our filings with the Securities and Exchange Commission. These forward-looking statements represent our judgment as of the time of the filing of this Form 8-K. We disclaim any intent or obligation to update these forward-looking statements, other than as may be required under applicable law.
